Preferably the inside walls of both the upper portion 5 and the lower portion 6 of the skirt are substantially vertical and parallel to the outside wall of the container.

It is also preferable that the upper portion 5 should extend downwardly less than half the total depth of the skirt.

While the invention has been described as applied particularly to containers comprising a paper or cardboard cylindrical body portion, it will be understood that it may also be useful in connection with containers made of other materials, particularly where such containers differ slightly in their outside diameters.

It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention:

1. A container comprising a cylindrical body portion of, compressible material such as cardboard, and a removable metal cover therefor, said cover having a circular disk top portion, and a skirt depending from the periphery of said disk, 9, portion of said skirt adjacent said top having an inside diameter slightly less than the normal outside diameter of said cylindrical body portion, so as to frictionally engage said body portion and slightly compress the same, and the lower portion of said skirt having an inside diameter slightly larger than the inside diameter of the upper portion of the skirt.

2. A container comprising a cylindrical body portion of compressible material such as cardboard, and a removable metal cover therefor, said cover having a circular disk top portion, and a skirt depending from the periphery of said disk,

as to frictionally engage said body portion and slightly compress the same, and the lower portion of said skirt having an inside diameter slightly larger than the inside diameter of the upper portion of the skirt, the inside walls of said skirt be ing substantially vertical and parallel to the out side wall of the said body portion of the container except for an offset portion joining the two portions of different inside diameters.

3. A container comprising a cylindrical body portion of compressible material such as cardboard, and a removable metal cover therefor, said cover having a circular disk top portion, and a skirt depending from the periphery of said disk, a portion of said skirt adjacent said top having an inside diameter slightly less than the normal outside diameter of said cylindrical body portion, so as to frictionally engage said body portion and slightly compress the same, and the lower portion of said skirt having an inside diameter slightly larger than the inside diameter of the upper portion of the skirt and slightly larger than the outside diameter of said cylindrical body portion.

4. A container comprising a cylindrical body portion of compressible material such as cardboard, and a removable metal cover therefor, said cover having a circular disk top portion, and a skirt depending from the periphery of said disk, a portion of said skirt adjacent said top having an inside diameter slightly less than the normal outside diameter of said cylindrical body portion, so as to frictionallyengage said body portion and slightly compress the same, and the lower portion of said skirt having an inside diameter slightly larger than the inside diameter of the upper portion of the skirt, said upper skirt portion extending downwardly less than half the total depth of the skirt.
